| Feb 10, 2013 at 14:13 | comment | added | user9072 | Could you please retag to use "finite-groups" instead of "finite-group". This is the only question tagged finite-group while for the other there are many; it is standard to use pluralized forms. Thanks in advance. | |

| Sep 11, 2012 at 19:53 | comment | added | Alexander Chervov | @QfwfqTake vector space V over F_q, take M=V, N=V^* take any G\in GL(V), people say that would be an example... Fourtier transform will give isomorphism... I've heard this today, so I am not big expert... Another example I added in the post - Irr(G) and Conj(G) under Aut(G) - if I understand correctly | |
